ONLINE SPAM SOLUTIONS - WE STOP YOUR SPAM, YOU DO NOTHING!

They provide an amazing value for Spam/Virus filtering. Prices start at $9.95/mo. I found them through Google, and it has been the most amazing find ever. We run an Exchange server with 25 users. We used to see over 200,000 messages per day hitting our server. This of course caused delays in the SMTP engine, and generally bogged down our server. We now see less than 1500 message per day hitting our box, and NO SPAM! These guys have excellent customer service, and are easy to setup. I highly recommend them as a solution! Particualarly in your case for 50 users.
